High-safety hot-line work isolation device

The invention discloses a high-safety hot-line work isolation device which comprises a mounting shell, a lifting mechanism, a linkage mechanism and a quick mounting mechanism. The four side faces of the lower end of the mounting shell are rotationally connected with rotating supporting walls correspondingly, evenly-distributed fixing holes are formed in the upper ends of the end faces, adjacent to the mounting shell, of the four rotating supporting walls correspondingly, a mounting base is arranged in the middle of the lower wall face of the mounting shell, and a needle bearing is arranged on the inner side face of the upper end of the mounting base; thrust ball bearings are arranged on the inner side surfaces of the lower ends of the mounting seats; according to the high-safety hot-line work isolation device, the rapid installation mechanism is matched with the rotating isolation plate, an appropriate isolation area can be rapidly clamped according to the work requirement, meanwhile, the linkage mechanism is
